Application filed September 28, 1822. Serial No. 591,068.

To all whom it may concern:

Be it known that I. SIDNEY ALL- WRIGHT, citizen of the United States. residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements'in a Gauge;

of which the following is a specification.

tive to the coils.

' mobile relative to the coil spools of the magneto. The coils of the magneto of a Ford automobile are carried on a fixed: ring-like 'coil support-and the magnets are carried by thefly wheel and revolve therewith rela- The adjustment between the: fly wheels and the coils should be such that the faces of'the magnets will'be separated from the surfaces of. the coil spools V isbolted to an end-'flangeof the crankshaft and in order to obtain the exact adjustment 1 onethirty second ofan inch. The fly wheel it is often necessary to interpose thin shims between said flange and fly wheel. If too many shims are used the magnets willbe too far from the coil spools andif not enough shims are used said magnets will be too close to the coil spools so: that in-ordinary practice the fly wheel must be bolted ontothe flange. and if it is not then the proper distance from the spools it= must'be removed and additional shims added or removed.

This usually requires. the removal of the fly wheel, and its replacement a'number of times to get the exact adjustment. Inasmuch as the fly wheel isheavy it is a laborious task-to adjust it. The device herein described has been devised forthe purpose of obtaining the proper adjustment without the necessity of fastening'the fly wheel into place and then removing it one or more times in order to get the proper adjustment. Another object of the invention is to pro-, vide a simple gauge which maybe cheaply and easily manufactured and which is convenient in use.

With the above and other objects in .view' the invention has particular'relation to, certain novel features of construction and use,

an example of which is given in this specification and illustrated the accompanying drawings, wherein:' s

Figure 1 is a fragmentary side view of 5 "the motor block. showing the magneto coil support. attached thereto, and-the gauge applied as in use." Y

V Figure 2 shows a rear view thereof] Figure 3 shows an edge view partlyin section of the gauge and,

Figure t shows a plan view thereof.

In the drawings, the numeral 1 designates the motor block, and the numeral 2' designates the crank shaft whose rearendcar- 'ries the-circular flange 3 which is formed integrally therewith. To'thisflange the fly wheel-isfbolted. 'Thenumeral 4 designates the magnet coil support. Fastened to the rear face of this support are thelmagnetoTl coil spools 5' arranged in a circular row, 1-

as shown in Figure 2. The spools 5 support the coilsproper." The inner face of" the Lwheel carries the magnets and has,

a central circular socket to receive the flange, 7.

3. This construction is well known to those familiar with the.'Ford magneto. -When the fly wheel-is fastened to the flange 3 the p fa'ces of'the' magnets should bespa'oed from the coil spools one thirty second of an inch.

. tis diflicnlt to get this nice adjustment, and thin shims must'be interposed between the flange 3 andthe fly. .wheelin orderto obtain the proper adjustment. In order to deter-l mine the number of shims.- reouiired; with? outthefnecessitv of actually fastening the fly wheel to the'flan'ge 3; I have provided the gauge which willnow be described: Saicl gauge has a central plate 6 approximately circular and provided with a circular socket 7 to receive the flange 3 Opposing arms 8,

8 are formed'integrally with the plate 6 and when the gaugeis bolted 'to said flange 3 the free ends of. said arms will 'lieopposite opposing, coil spools. The opposing faces 9, 9 of the free ends of sai'd'arms-lie in the same plane and are ground smooth. By the use of shims, this gauge may be ad- .justed untilthe faces 9, 9 are spaced from o the coil spools one thirty second of an-inch.

The edge contour of the gauge is the same as across sectional contour of the fly wheeland when the proper adjustment is obtained the gauge may then be removed and the fly Wheel bolted onto the flange 3 and the faces of the magnets of the fly Wheel will then be spaced the same distance from the coil spools as the faces 9.

What I claim is A one-piece gauge formed With a central plate having a circular socket and radiating arms carried by said plate the free ends of said arms being formed with smooth faces
